[0065] The base plate 9 is provided with feet 9-1, which facilitates placing the throttle body clip mounting device on the workbench 10 and facilitates moving the throttle body clip mounting device.

[0066] See Figures 1 to 14 In specific embodiment 3, this embodiment 3 provides a snap-fit ​​installation device for a throttle valve. The difference between this embodiment 3 and the previous embodiment is that: a magnet 6 is provided in the positioning block 5. The positioning block 5 can attract the snap-fit ​​1 (the snap-fit ​​1 is made of metal, such as stainless steel) and help fix the snap-fit ​​1 on the positioning block 5. This avoids the snap-fit ​​1 on the positioning block 5 from shifting position or slipping off, which would affect the installation of the snap-fit ​​1 and also improves the efficiency of snap-fit ​​1 installation.

[0067] Preferably, a magnet 6 is injection molded into the first side portion 5-1 corresponding to the first inclined surface 5-1-1 and a magnet 6 is injection molded into the second side portion 5-2 corresponding to the second inclined surface 5-2-1. This increases the adsorption effect of the positioning block 5 on the buckle 1 without affecting the operation of placing the buckle 1 on the first inclined surface 5-1-1 and the second inclined surface 5-2-1.

[0068] Alternatively, the positioning block 5 can be made of magnetic material, which can also achieve the adsorption of the buckle 1 by the positioning block 5, and will not affect the operation of placing the buckle 1 on the first inclined surface 5-1-1 and the second inclined surface 5-2-1.
